Puritan 156 and Furman

I am currently using a Puritan 156, and was thinking of putting my Furman back into the mix, I know I have to try it so I won't ask if it will improve anything. So I would plug the Puritan into the Furman.

My question is any possible negatives doing this? Here is the unit I have.
